To all whom it may concern.-

Be it known that I, ISAAC N. GLAUBER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in \Vaste Cocks; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to waste-water cocks; and the object of theinvention is to provide a waste-cock which, if it be set by mistake ininverted position, can be easily righted without removal. Heretofore, aswastecocks have been generally constructed, there was only one way inwhich they could be set and work, and if by accident or mistake the cockwas set in inverted position it had to be bodily detached from the pipesand placed in right position before it could be used for waste purposes.

My invention renders detachment and reversal in case of mistakeunnecessary, and enables anyone, however unskilled, to correct the errorand make the cock work right, even though it remains in invertedposition.

To these ends the invention consists in the construction and arrangementof parts substantially as shown and described, and particularly pointedout in the claims.

In the accompanying drawings, Figure 1 is an elevation of a waste-cockconstructed according to my invention, and broken out in its upperportion to reveal the parts as they appear in wasting position. Fig. 2is a vertical sectional elevation on line 2 2, Fig. 1, through thecenter of my improved structure. Fig. 3 is a cross-section on line 3 3,Fig. 1, showing the stop-screw in normal position as it appears when thecock has been set properly. Fig. at is a cross-section on a linecorresponding to 3 3, Fig. 1, and showing the parts as when the cock hasbeen set in what may be considered as inverted or wrong position, andshowing the stop-screw driven in to overcome the error and enable thecock to work right, as hereinafter more fully described.

A represents the casing or body, and B and O the pipe connections uponwhich the body is secured when in working position.

D is the plug or valve, which is of the usual cylindrical and taperedform common in this art. Broadly, the plug and the body are old and wellknown. The plug has the through water-passage 2, and the waste is fromabove through the inlet or opening 3 in the side of the plug and theoutlet or discharge 4i in the side of the body, as seen in Fig. 2, andwhich also is old and well known. Figs. 1 and show the same relation ofparts.

Always heretofore the plug D has had a certain limited quarter turn witha stop to determine its rotation to open the plug for the free passageof water through the pipe or to turn it off and open the waste, as hereshown. But this was the limit of the function of the stop, and there wasno provision whereby when a plug was wrongly set to make it operate justas well as if it had been set aright. My invention is designed toaccomplish this result, as above indicated, and to this end I form thebody A within the mouth of the barrel for the plug with a segmentalgroove or depression 6, having shoulders at its ends and extending abouta third or more around within the barrel. A corresponding groove ordepression 7, with shoulders at its ends, is formed in the plug Dopposite depression 6, but shorter, and having at one end a threadedhole or cavity 8. This threaded cavity is diametrically opposite thewaste-passage 2 in'the plug, but farther out. A threaded hole is made inthe body which taps the groove or depression 6 at the end next to thethreaded hole 8 at the end of groove 7, and into this hole in the body Iinsert a stop-screw 10. This screw has no head and is of such length asin the first instance to reach through into the groove 7 in the plugwhile its outer end retains its bearing and hold in the body A, thusworking between the shoulders in groove 7 and serving as a stop to therotation of the plug. \Vhen the parts are as seen in Figs. 1 to 3, theplug has been rotated into position to open the waste-passage. This isthe limit of rotation in one direction. Then by turning the plug backtill the screw strikes the opposite shoulder of the groove 7, the wastewill be closed and the through passage 2 for the water open. The portion14 of the plug will then close the waste-passage 4, and the threadedcavity 8 will be opposite the stopscrew 10. This shows what may betermed the proper relation of the parts and how they should work whenthey have been set in this way. But suppose when one comes to turn thewater off for the first time he discovers that the cock has been setupside down, as frequently occurs. found that the waste-inlet 3 of theplug will be on the right, as seen in dotted lines, Fig. i, and the onlypossible turn of the plug will bring said inlet 3 to the bottom and openthe discharge to the water in pipe 0, which is open to the main. Hence,it would be impossible to waste the water out of the pipes if all theparts remained as shown in Fig. 3. However, with the parts as seen inFig. 4, it will be seen that the screwlO is in position to thread downinto the cavity 8, as has been done in this figure, so that it is nowtransferred from the body A to the plug Dand will rotate therewith. Now,having transferred the screw from the body to the plug, it moveshereafter with the plug, and its opposite or outer end now operates as astop against the shoulder or ends of the groove or depression (3 in thebody. This done, the plug can now be turned in the reverse direction farenough to bring the waste-passage 3 above again and in communicationwith the water to be wasted, as in Fig. 2. The parts will now work aswell as originally, only in turning to *aste position the plug will haveto be turned in the opposite direction. Obviously,

if preferred, this latter position of stop-screw 10 might be made thepreferred position, in which case to change or reverse the action Inthat case it will be the said screw would be run out so as to be andoperate as in Fig.

It will be thus seen that the screw-stop 10 is interchangeable betweenthe parts A and D and that it operates equally well in both the grooves6 and 7.

The plug is held in working position and can be tightened therein by thenut at its smaller end.

\Vhat I claim is-- 1. The body and the plug having opposite threadedholes and shoulders to be engaged by a stop, and a stop constructed tooccupy either of said holes and to work between said shoulders,substantially as described.

2. The body and the plug therein and each of said parts constructed tolimit the rotation of the plug, and a stop movable bodily from one ofsaid parts to the other, substantially as described.

3. The body and the plug having each a segmental groove and a threadedstop constructed to engage in either of said parts and operate in eitherof said grooves, substantially as described.

at. The body and the plug having opposite grooves and opposite holes fora stop, in com bination with a stop occupying one of said holes and oneof said grooves, substantially as described.

WVitness my hand to the foregoing specification on this 7th day ofDecember, 1895.
